To all whom it ma concern:

Be it known that EDWARD A. RUssnLL, a citizen of the United "States,'anda resident of Chicago, in the county of Cook and State of Illinois, havemade certain new and} useful Improvements in Valves, of which the,following is a specification.

My invention relates to a multiple port valve device or circulationcontroller of the rotary t pe for governing the circulauid through apipe system; this application bein a division of my co-pendingapplication erial No. 434,179, filed Defor automatic car heating stems,in which the valve device is eml iloyed to automatically control theinflow of steam to and the discharge of medium, including water ofcondensation, from the radiating coil of the car heating apparatus.

A principal object of the invention is to provide a new and improvedvalve device, or circulation controller of this character suitable foruse in the above mentioned or analogous situations. A particular objectdevice that water of condensation may be discharged therethrough from anintermediate point in the radiat' coil as well as from t e discharge endof t e coil, while the device is set for admittin steam to such coil.

A furt er ob'ect of .the invention is to provide a nove and improvedelectrically actuated mechanism for shifting the valve from one positionto the other.

A further object is to provide for hand operation of the valve in casethe electric apparatus is accidentally or intentionally disabled.

objects and such other manufacture and install.

A further object is to provide an actuat ing means for the valve whichwill be compact, positive and reliable in its action, economical tosimple in construction and I The invention consists in the new andimproved arrangements, constructions and devices to be hereinafterdescribed and claimed for carrying out the above stated incidentalobjects as will be mentioned in the description that follows of thepreferred embodiment of the ating coil 0 I0. 484,179. iliivided and thisapplication fled 1,448,878, dated January :8, 1988. Applicationinvention shown in s. a

F'g. 2 is a side elevation thereof witha hood broken away to show in theaccompanying drawg'firsttoFigs. 5 and 6, A isthe steam train pipe of arailway car, the radiwhich is shown as consisting of two sections B andC. D is the circulation controller of the radiator, E and F the motorsoperating the same, G the. va r lator, H the limit switch for switchingt e current alternately to motors E and F, and Q the battery for supplelectric current.

The circulation contro er or valve device is preferably constructed asshown in Fi 's. 1, 2, 3 and 4-. jis a. casin divided y mterior webs intoa central circular space 26, in which is arranged a rotary valve 27 andaround said circular space mto a plurality of chambers which forconvenient reference will be 'ven the following somewhat arbitraryiesignations and are numbered on the drawings as follows: 28 is a supplychamber connected by ipe 34 with the train line A; 29 is a disc argechamber connected by pipe 39 with the thermostat chamber of the va rregulator G; 31 is an inlet chamber 0m which leads the inlet pipe 35 ofradiator section B; 32 is a first return chamber to which extends adrain radiator section B; 30 is a second return chamber to which leadsthe return end 38 of radiator section 0; and 33 is a drip chamber havinga port communicating with a drip pipe 41.

'10 VAPOR CA3 HEATING- pipe 36 from the return end of 06 v formed in thecasin against the'escape of steam.

The first chamber 32. is connected with the discharge chamber 29 by aduct 40 under the above mentioned chambers. his duct 'might extend tothe second return chamber 30 instead of to discharge chamber29 since, aswill appear, chambers 29 and 30 communicate with'each other at suchtiines as the duct 40 is necessary for the proper operation of thecontroller. This duct is arranged .so as to be water sealed The valve 27comprises a lower disc 42, an upper disc 43 and webs 44, 45 and 46, theupper disc being formed with a stem 47 extending throu a bonnet 48 onthe top of casing 25 and ufil: a packing1 50 and packing gland 51. estem 47 as fixed thereto a lever 52 terminating, preferably,

in a handle 53. 54 is a pivot stud onthe lower disc 42 which fits arecess 55 in the bottom of the casing. The lever 52 is formed with awidened ortion 56 having curved edges 56, 56" an this portion of thelever is byapairofheads57',57formed on e unita structure 58 forming thecores of the so enoid motors E and F. The opposite:1 end 59 of (lever 53is proviilled with a e din gstu 60 engaging aco ar 61 on the za w itchmember 62 of limit switch H. This switch member is composed of msulatingmaterial and slides in suitable openings in block 63. A pair of springcontacts 64, 64" secured to one of the blocks, 63*are adapted to bearagainst the contact 65, 65 on member 62, these plates electrical]connected by rivets'66. Secure to the 0 er block 63 1s a similar pair ofcontact springs 67, 67 adapted to e age the contact plates 68 on thecorrespon g end of mem r62. Thea entissuch that when the contact springs67, 67 bear against the lates 68, 68, the contact plates 65 are out otouch wlth'sp 64, 64" and vice versa. 69 is a hood on e top 0 casing 25enclosing the inner ends of the solenoids and the hmit switch.

The vapor regulator G is a device in common use .for maintaining thesteam in the radiator at substantially atmospheric pressure. For detailsof construction reference is made to the patent to Gold 1,077,525, Nov.4, 1913. In the present connection it will be suficient to state thatthe device comprises a pressure redu valve 70 arranged inavalvecasing71w 'chisinterposedinthe sufiply pipe 34. Valve 70 isoperated by a be crank 72 tofiwhigi is afich pd 51:11am 73 bearing uponaexi ecap e 4 with a liquid which expands under heat. This capsule orthermostat is arran d in a thermostat chamber 75 to which amipe 39leads. Outflow of live steam ugh ipe 39 explandsthermostat 74,throttling own valve 0 to'limit inflow to the radiator.

From pipe 34 steam through chambers 28, 31, gipe 35 o coil B,through radiator section into pipe .37 of radiator section C and throughradiator section 0. The water of condensation outflows from radiatorsection B through pipe 36, first return chamber 32, duct 40, dischargechamber 29 and pipe 39 to the thermostat chamber 75 of the vaporregulator G. Duct 40 is sealed against the escape this wa of steam.Water of condensation (an steam incertain quantities when the system isworking at capacity). outflows from radiator section 0 V rough pipe 38,second return chamber 30, discharge chamber 29 and pipe 39- When the cartemperature has reached a certain point valve member 27 is rotated bymotor F through the operation of certain thermostatically actuatedcontrolling devices which are shown in my co-pen ap lication Serial No.434,179 above re one to but which form .no part of the presentinvention. These devices serve, when actuated, to close a circuitthrough motor F as follows: battery Q, wire 139, windin of solenoid F,wire 140, contact spring 6 contact plate 68, contact spring 67 wire 141to the batte the thermostatically actuated controlling evices beingconnected with the wire 141 at the place, for example, indicated by thebroken lines. So far as the present invention is concerned, any suitablemeans might btla employed for closing the circuit at this p ace.

The valve 27 and limit switch H are'now moved so that the other chambersare all in communication with the drip chamber 33. Steam now flows frompipe 34 directly to 39, and, by operation of the pressure just enoughsteam follows course to' keep the vapor regulator warm as a 'ainstfreezing, without wastage. Water 0 condensation from the inlet pipe 35and from the return pipes 36,38 outflows through the (in pipe 41. Duct40 is water sealed so that wit the low pressure of steam handled there uchamber 29 1nt d the radiator.

The limit switch, it will be observed, is moved b the valve itself so asto alternately direct tli e current to the motor operating solenoids Eand F.

The expedient of formin the portion of lever 52 engaged by heads 5 witha widened portion having curved edges, as described above, has theadvantage of utilizing most eflectively the force developed by thesolenoids E and F for moving the revoluble member of the valve and thereciprocating member of the limit switch without sacrificing compactnessand simplicit of structure. The arrangement is suc that the leverage ofthe solenoid coil structure on the parts moved is at'a miximum duringthe beginning of each anglular movement of the lever, at which time t epull of the solenoid.

is necessarily weakest and the resistance to be overcome, due to inertiaand friction of the moved parts the greatest, this initial leveragebeing gradually decreased as the movement of the lever progresses. Thiswill be apparent from consideration of Fig. 1. Assuming that solenoidF'is energized so as to draw the core structure. in this direction, theinitial engagement of head 57 with the curved edge 56 of the lever is ata point on the other side of the axis of the solenoid core from the axisof rotation of the valve, the ivotal axis, that is, of the lever. Theorce which the solenoid exerts upon the valve and limit switch is,therefore, considerably greater than if the point of engagement betweenthe lever and the core were at the axis of the core. After the inertiaof the initial friction of the parts has been overcome and the movementof the lever p the oint of bearing of head 57 on the lever shi sinwardly toward the axis of rotation of the lever, the leverage beingconsequently diminished and the lever finally brought to a positionwhere the head '57" is ready to engage the edge 56" of the lever at aint of maximum remoteness from the axis of rotation of the lever. Theresult of this arrangement is that the valve operating mechanism may bemade relatively small and compact and a smooth, even movement of theactuated parts is obtained. A relatively short lever may be employed,relatively small coils may be used and the electro-motive forcesrequired reduced to a The valve 27 has been referred t as being in theopen position when turn to admit point, motor E is ener ized to .thereturn and dischar position esta the sup ly and discharge chambers andbe-' steam to the radiator and direct outflowing medium to thethermostat chamber of the vapor regulator as shown: in Fig. 5; By ferrinto the valve as in the c os'ed position these terms being 11 somewhatarbitrary in a valve device of t is sort) I intend the ition of thevalve as shown in Fig. 6 in w ich the steam is short circuited to thevapor regulator. These terms may have to be construed in a relativerather than in an absolute sense in case, as is within the scope of thepresent invention, the controller is put to a use different from thathereinabove described. 1
